The P1456D135VIB round arch frame is a premium architectural element designed to frame doorways, windows, and main passageways with historical elegance. Featuring a grand semi-circular curve and an ornate acanthus leaf keystone at its apex, this decorative structural element instantly elevates the architectural value of any building. It serves as a sophisticated alternative to heavy stone or fragile plaster arches, delivering both durability and ease of handling.
Engineered from rigid Poliüretan with a density of 150-200 kg/m³, this arch frame provides the physical resilience of hardwood while remaining remarkably lightweight. With a generous width of 1750 mm, a height of 944 mm, and a deep profile of 211 mm, it offers a substantial three-dimensional presence on both interior walls and exterior facades. The closed-cell structure of the material ensures it remains entirely impervious to water, moisture, and rot, making it highly reliable in all climate conditions.
Visually, the product showcases a flawless, smooth-curved profile that contrasts beautifully with the highly detailed, classical floral scroll on the central keystone. This balance of clean lines and intricate ornamentation allows the arch to integrate seamlessly into traditional, neoclassical, or eclectic architectural styles, adding depth, shadow lines, and structural character to flat surfaces.
In terms of application, this arch is highly versatile. On exterior facades, it serves as an impressive window pediment or entrance header for luxury villas and estates. Indoors, it can be used to define transitions between grand hallways, living rooms, or hotel lobbies, creating a sense of flow and scale. It is also an excellent decorative choice for framing deep wall niches or highlighting classical fireplace mantels.
The arch frame comes pre-finished with a factory-applied primer that prepares the surface for painting. While this layer facilitates paint adhesion, applying an additional primer remains optional and is subject to the recommendation of your chosen paint manufacturer for warranty purposes. For a secure installation, the segments must be mounted using a high-quality poliüretan (PU) montaj yapıştırıcısı and reinforced with mechanical screws, followed by a final coat of UV-resistant paint to protect the material from sunlight exposure.
- This decorative round arch frame is designed for high-end residential and commercial projects
- On exterior facades, it is ideal for framing arched windows and main entrance doors, creating a majestic focal point on classical villa walls
- Indoors, it excels as a transitional element in grand corridors, hotel lobbies, and classical restaurants, defining open passages without blocking natural light
- Additionally, it can be used to frame deep wall niches, library shelving units, or as an ornamental topper for large fireplace mantels in luxury living rooms
- Ensure the mounting surface is clean, dry, and level
- Position the arch pieces and the central keystone to check alignment
- Apply a generous amount of poliüretan (PU) montaj yapıştırıcısı to the back of the polyurethane elements
- Press firmly onto the wall and secure mechanically with screws to ensure long-term stability while the adhesive cures
- Fill any joints and screw holes with an exterior-grade acrylic filler, sand the surface with 180-220 grit sandpaper once dry, and apply your choice of premium paint
- For outdoor installations, a UV-resistant topcoat is mandatory
- Maintenance is minimal
- For interior installations, dust regularly or wipe with a damp cloth
- Avoid using harsh chemical solvents or acidic cleaners
- For exterior applications, inspect the paint surface annually to ensure the UV-protective coating remains intact, and repaint if weathering is visible
- If accidental impact occurs, the material can be easily repaired with standard wood filler, sanded, and repainted
